Firewall Quiz: Can You Master IDS Vs IPS?

1. What is a false positive in the context of IDS/IPS systems?

A legitimate activity incorrectly flagged as malicious

A missed malicious activity

A system error during packet inspection

An IDS failure to connect to the network

2. What is the primary advantage of a next-generation firewall (NGFW) over traditional firewalls?

Lower cost and easier configuration

Application-layer visibility and threat prevention

Support for older operating systems

Requirement for no updates or patches

Submit

4. Which scenario best requires an IPS rather than just an IDS?

Monitoring compliance violations only

Real-time prevention of zero-day exploits

Generating alerts for administrative review

Logging network traffic for forensics

Submit

7. Which of the following best describes a proxy firewall?

It inspects packet headers only

It acts as an intermediary between clients and servers

It uses only MAC address filtering

It operates exclusively at Layer 2

Submit

9. Which detection method does IDS/IPS use to identify known attack signatures?

Behavior-based detection

Signature-based detection

Anomaly-based detection

Heuristic-based detection

Submit

11. Which layer of the OSI model do stateless firewalls primarily operate on?

Layer 2 (Data Link)

Layer 3 (Network)

Layer 4 (Transport)

Layer 7 (Application)

Submit

13. Which firewall technology uses deep packet inspection (DPI)?

Stateless packet filter

Next-generation firewall (NGFW)

Circuit-level gateway

MAC filter

Submit

15. Which of the following is a disadvantage of IDS in passive mode?

It cannot detect malicious traffic

It cannot prevent detected attacks in real-time

It requires more processing power than IPS

It cannot generate alerts

Submit

17. IPS systems typically operate in which mode to block detected threats?

Passive mode

Detection mode

Inline mode

Logging mode

18. Which firewall type can inspect encrypted traffic content?

Packet filter firewall

Circuit-level gateway

Application-level gateway (proxy)

Stateless firewall

Submit

20. What is the primary difference between IDS and IPS?

IDS blocks threats; IPS only alerts

IDS detects threats; IPS detects and blocks

IDS monitors outbound traffic only

IPS requires manual intervention after detection
